Functional Description
Automatic Page Write
Page-mode write feature allows 1 to 32 bytes of data to be written into the EEPROM in a single write cycle.
Following the initial byte cycle, an additional 1 to 31 bytes can be written in the same manner. Each
additional byte load cycle must be started within 30
μ
s of the preceding rising edge of the
WE
. When
CE
or
WE
is high for 100
μ
s after data input, the EEPROM enters write mode automatically and the input data are
written into the EEPROM.
Data
Polling
Data
polling allows the status of the EEPROM to be determined. If EEPROM is set to read mode during a
write cycle, an inversion of the last byte of data to be loaded outputs from I/O7 to indicate that the EEPROM
is performing a write operation.
RDY/
Busy
Signal
RDY/
Busy
signal also allows the status of the EEPROM to be determined. The RDY/
Busy
signal has high
impedance, except in write cycle and is lowered to V
OL
after the first write signal. At the end of a write cycle,
the RDY/
Busy
signal changes state to high impedance.
